Specifications
Frequency range
Mode
Internal oscillators, external oscillator, FREQUENCY METER
Internal oscillators
50 Hz, 60 Hz, 400 Hz: Fixed frequencies
VAR:
Variable frequency 40 Hz to 1000 Hz (0.001 Hz resolution)
External oscillator
Using the synchronous operation input terminal
EXT1:
Receives a single signal
EXT2:
Receives two signals (90° phase difference), phase shift feature available
Phase shift range –180.000° to +359.999° (0.001° resolution)
FREQUENCY METER Assign sweep, output divider, and deviation output features to frequencies
MIN:
Lower frequency limit
MAX:
Upper frequency limit
Upper and lower frequency limit range: 20 Hz to 1000 Hz (resolution is the same as VAR)
Lower sweep frequency limit:
20 Hz
Upper sweep frequency limit:
1000 Hz
Sweep function
Target
Deviation and output divider settings and their related voltage, current, and frequency
Speed
0% to 100% or 100% to 0% of the setting; select from approx. 8 s, 16 s, 32 s, 64 s
Output divider feature
1
Target
Voltage, current, frequency
Denominator range
m : 4, 5, . . . 15 (12 divisions)
Numerator range
n : 0, 1, . . . 15 (where n ≤ m)
Deviation output feature
1
Source
Voltage, current, frequency
Variable range
±20.00%
Setting method
Two dial setting
Resolution of dial 1: 0.2% of main setting
Resolution of dial 2: 0.01% of main setting
Preset feature
5%
The deviation is set to ±5% when the preset value is changed or when the output divider n is changed.
(+5% when increased, –5% when decreased)
2%
The deviation is set to ±2% when the preset value is changed or when the output divider n is changed.
(+2% when increased, -2% when decreased)
0
The deviation is reset to 0 when the preset value is changed or when the output divider n is changed.
OFF
The deviation is held. (Preset is not applied.)
1
Equation for setting (setting) = (main setting) X (n/m) + (main setting) X (–deviation)
The upper output limit is obtained by adding 20% to the value given in section 16.1, “Range Generated.”
The accuracy is according to section 16.2, “Accuracy.”
Output terminals

Voltage: Plug-in terminal (safety terminal)
Current: Large binding post
Output LO terminal
Ground or not ground selectable
Withstand voltage to ground when open: 12 Vpk
